Causes of roof leaks during rain

Numerous leaks are caused by old or incorrectly installed roofing systems that have aged, degraded, cracked, broken, or been damaged, creating spaces where water may enter. When the rain begins to fall hard, it will make its way into any little or big holes, cracks, or any other place where water may reach, particularly if you have an older roof or one that has several repairs or patches. If possible, take photographs of all the roofing and exterior damage if possible; this will assist you in obtaining insurance coverage for a roof replacement.

Roof leakage inspection

If it does not leak under mild rain, this does not necessarily indicate that it does not leak. Generally, any spot where water may enter is in danger of creating damage to your structure, whether it’s mold on your rafters or roof decking or water damage that goes undetected from within the home. Minor leaks can become huge leaks that may swiftly cause substantial damage, therefore don’t allow a little leak to become a major leak.

Immediately Stop Your Roof’s Leakage

The best strategy to stop roof leaks during heavy rain is to determine what caused it in the first place so that you can avoid future leaks in your house.

Certain cover alternatives are more suited to the immediate protection, while others assist your roof in keeping your inside dry over time. Additionally, it pays to be aware of the kind of storms you anticipate.


 Numerous residences and commercial buildings, particularly those with flat roofs, have some kind of plumbing protruding from the roof. When pipes are installed through the roof, the hole around the pipe must be carefully patched and sealed to prevent water from entering. Over time, the sealant may fail, allowing for the formation of tiny penetrable regions and subsequent leaks. Ensure that you inspect any plumbing on the roof for potential damage.


The most often seen issue is “Roof vent leaks during heavy rain”, typically, your roof will have multiple vents that enable heat from the stove, bathrooms, or attic ventilation systems to escape the home. If the contractor who installed your roof did not properly seal the edges around the vents, or if your vents become damaged or bent, there may be areas where water can enter your home. It is critical to ensure that your roof is installed correctly in the first place and is properly maintained to avoid future leaks.

Water Ponding:

On flat and low-sloping roofs, water ponding is a frequent occurrence that becomes considerably worse during periods of heavy rain. When a large volume of water accumulates, it creates a vast surface area and will reach regions of the roof that it typically does not, causing it to leak. Seals and patched areas on flat roofs are more prone to leaks, so these locations should be checked first.

Clogged Gutters:

If your gutters get too clogged with leaves and debris, they will prevent water from flowing efficiently away from your property. When gutters are clogged, rainwater overflows and may enter the property, causing siding damage and foundation problems. Ensure that your gutters are clean and effectively diverting water away from your property without becoming clogged, or you may have some unwelcome water damage.

Solar Panels:

While having a solar panel system installed on your property might save you money, if the installation is not done properly, there are several spots where the panels are fastened to your roof that could leak. Each mount must be properly connected to the roof, which implies that several screws will pierce the roof, and each screw hole represents a possible leak source. Check your attic for leaks around the solar panels’ mounting locations.


Chimneys are often poorly maintained, and after years of age and degeneration, the chimney may acquire issue areas such as cracks in the bricks or cement. As with everything else on the roof, good flashing installation around the chimney will keep water out of places it shouldn’t be. If you detect cracks in your chimney, contact a professional or repair it yourself as soon as feasible.


Skylights are excellent for bringing light into your house, but they may also be excellent for allowing water in. The older the skylights, the more vulnerable they are to hail and debris damage, not to mention leaks around the skylight’s borders. Using an ice and water barrier around the edges can help avoid these problems, but if the roof decking is rotted through, leaks will occur regardless as the water makes its way through those spots.

Damaged Roofing:

Old roofing materials deteriorate over time, posing a significant concern for property owners. When paired with heavy winds, most roofing materials will expand and contract somewhat during temperature changes, causing the material to fracture, tear apart, and even fall off the roof entirely. Metal roofing may corrode with time, allowing water to enter the gaps or screw holes used to connect the panels. In violent thunderstorms, hail may cause tile to shatter and shingles to be blown off. Don’t allow old, damaged roofing to cause you extra difficulties; instead, get your roof evaluated on a regular basis to avoid these issues.

Snow Melt:

After a heavy snowfall, the ice and snow on your roof will begin to melt, and if this melt seeps into any gaps, you will experience damage. This isn’t the same as what you could see from heavy rain, but water on your roof is just as dangerous if it gets inside.

Too Much Weight:

If your roofing system is too heavy for the structure of your building, you may notice some drooping of the roof, which may lead to serious problems with the whole roofing system, not to mention the risks of having people beneath such an unstable roof. Some unlicensed builders will not take adequate measures while installing your roof, and if you wind up hiring someone who is unaware that your structure isn’t fit for a hefty roofing system, you may be faced with a full roof replacement process. A roof that is excessively heavy and saturated with water may begin to leak, which is your first indication that it needs to be repaired.


Broken branches and debris dropping on your roof during storms may cause major damage and, if not addressed immediately, can enable a lot of water to enter your home, which is never a good thing. After a major storm, always inspect your roof to ensure that nothing has fallen onto it.

Hail Damage:

Hail is a typical issue in Colorado, and it wreaks havoc on roofs. Large hailstones may shatter your shingles, dent metal roofs, fracture tile roofs, and even make holes in your roof. Even slight hail damage may create cracks in your roof structure, allowing water to get underneath and ultimately cause a leak. If there is no visible evidence of serious damage yet your roof continues to leak after heavy rains, this might be the cause.

Improper installation of the roof:

Unless your roof was damaged by any of the things on this list, your roof leak is most likely caused by the way your roof was put on the last time it was replaced. If you don’t do your research and follow our checklist for hiring a roofing contractor, you might not be able to tell which contractors are legitimate. There are so many unlicensed and poorly-trained contractors out there that it can be hard to tell which ones are legitimate. You’ll usually have to pay twice as much when you hire the cheap guy.

How To Repair A Roof Leak:

Temporary Fix:

If water is flowing into your house, the first thing you should do is find a means to collect it and prevent it from inflicting more damage to the inside of your property. Collect buckets, containers, bowls, bottles, and anything else you can to collect as much water as possible, since water-damaged walls and floors are very costly to restore. Then go ahead and drape a tarp over the leaking areas to prevent more water from entering. Weigh down the trap’s corners to prevent it from blowing away. You may want towels or something similar to assist in preventing water from entering major holes in the roof. Because each roof leaks during heavy rain are unique, you’ll need to assess the situation and decide how to proceed until the roof is repaired.

Take Care Of Your Belongings:

If water is flooding the home or pooling on the ground and you are unable to stop it, quickly remove any valuables. Additionally, you may use towels or sandbags to assist control pooled water if you have some lying about.

Extract Standing Water From The House:

If there is any standing water in the house, you should immediately get out the shop vac and suck up all of the standing water. If you don’t have anything to clean it up with, you may want to consider hiring a water extraction firm to come quickly and remove all of the water.

Examine The Remainder Of The Property:

Just because you fixed one leak does not mean the rest of the house is leak-free. It is usually a good idea to inspect the remainder of your home for leaks or evidence of the damage as well, since there may be other issue areas to address. Examine the attic for black patches, water damage, or mold growth, since these are all frequent symptoms of a leaky roof.

9 methods to try to fix a leaky roof

These techniques will allow you to enjoy dry rooms before, during, and after rainstorms. The top causes of roof leaks during heavy rain are:

1.  Take Care of the Interior of Your Home

Before anything else, take care of the inside of your home. Begin by putting a bucket, pan, or bowl beneath the leak to catch any seeping water into the residence. By the time you detect the leak, water has probably landed on the floor, furniture, or other items.

If the leaking water has somewhere to fall, you’ll then need to dry up any wet areas. Dry the floor and any other wet spots using a towel to prevent slipping and water damage to your items.

After drying any damp surfaces and catching any leaking water, attempt to determine the source of the roof leak.

During the wet period, some parts of your ceiling may seem darker than the rest. Take some photos of the dark spots on your ceiling so you can show these to your roofing contractor later. This will help your roofer better identify where the problem may be coming from.

2: Try to Discover Where the Rain Roof Leak is Coming From:

To stop a ceiling from leaking, you must first identify the source of the leak. This will save you time and money on tools needed for repairs and fixing multiple leaks.

This part can be a little difficult, especially if you’re not exactly sure what you’re looking for. But if you can see if you are able to find out where the leak is coming from. Common causes of roof leaks are related to plumbing as well as AC units. However, if you’ve never had a leak before except when it rains, it’s likely due to a roofing issue. Other potential sources for leaks include clogged gutters, pest infestation, and issues with heating, and cooling units.

Check the tiles and drywall on your roof and ceiling to see if there is any damage. When you inspect certain areas, it may be common for leaks to occur there if there is an imbalance.

If the weather is not too severe, grab an umbrella and have a look at your roof while it’s raining. It may be possible to identify the source of the water entry if you can see it.

Are your gutters clogged? This is also another common cause of a leaky roof. When gutters are clogged, water builds up because it has nowhere to go. As a result, it can often find its way into your roof, seeping in. Check for gaps in flashing, around vents, or on the slopes of your roof if you have a chimney.

Pay attention to your home’s exterior as well, as rainwater may find another way in.

Note your findings so you may discuss them with a roofing contractor when they come to inspect your roof.

3. Clear the area:

Once you have an idea of where the leak is coming from, you can prepare the area for repairs. By clearing out the area where water would come in, you can stop roof leak damage and know quickly if a leak is present.

You can mop the wet area under the leak and place pails to catch extra water coming through the roof. Suction hoses come in handy for leaks that are coming through a floor above you.

Don’t forget to move furniture and other appliances out of the way of the leak. If the furniture is too heavy or difficult to move, then cover it with plastic covers to keep them dry.

4. Have a Look in the Attic:

Another place to check is inside your attic. If you can readily reach your attic, grab a flashlight and go up there while it’s still pouring. If there is built-in lighting in your attic, even better. No need for a flashlight.

Similar to observing the exterior of your home, you are also looking for problem areas here. Do you hear water dripping? Can you see water entering from anywhere or notice any wet areas? These are things to look for as they can be indicators of where your rain leak may be coming from.

Pat your hand around the insulation. Are some areas wet and others dry? Knowing where water accumulates may help you determine where it enters.

Either way, keep a few mental notes and snap a few more pictures if anything unusual stands out to you. While a roofing specialist may undertake a more comprehensive inspection, any background information will help them focus their search.

The goal is to call a roofer as soon as possible since flooding anywhere in your house. This may lead to major issues like mildew and future repairs.

Learning that your roof has a leak after rain or a thunderstorm is never fun. We understand that. But left unattended, it can lead to serious roof damage.

5. Apply Roofing Tar:

If you do not have tar on your roof then you need to install it for preventing water leakage. In addressing how to fix a leaking roof from the inside, you must first assess the outside of your home. One way to do that is by keeping the roof tiles in good shape.

That’s where roofing tar patches, which work best for removable tiles, can help. You can take the tiles off to find internal leaks, and roofing tar can seal the leak in the inner ceiling.

Roofing tar can perform better with support from material such as a piece of shingle or plywood. You can push the shingle or plywood against the area with the leak and then apply roofing tar to keep the spot dry.

6. Use PE Plastic:

Covering leaks from difficult sources is the best idea. It is harder to find. A prime example is polyethylene (PE) plastic, which can limit the amount of space affected by leaks and can catch water trying to get in.

All you need is a ruler to measure how much PE plastic you need to cover the leaking area. We advise giving your plastic three to four extra feet to minimize future leaks as much as possible.

Next, use staples to attach the plastic to the area and then nails to keep the plastic in place. Keep your PE plastic as thick as possible so that you can shield your rooms from as much water as possible.

7. Install New Shingles:

The condition of your shingles also affects how effective your roof can stop a leak. Shingles with curls, bruises, and pieces missing make it easier for water to get into your home from the outside.

Make sure to wear proper safety gloves to avoid cuts when removing older shingles. Before you climb up the ladder to get to the leaking area, put on rubber boots to avoid slipping.

Remove the old and broken shingles with a straight edge and hammer’s nail removal hook and apply the replacement with nails and roofing tar. This works best as a temporary fix until you find a more durable shield from the rain.

8. Use Tarpaulins:

Some of you may expect a storm tomorrow and need a quick fix to your roof leaks during heavy rain. One method is to install a tarpaulin, which can cover up areas that you suspect to have exterior leaks.

The amount of tarp you employ will depend on the number of leaks and the size of your roof. Utilizing numerous tarps is useful when a roof has many leaks in various places.

We suggest anchoring the tarp with hefty concrete blocks and stretching it over the ridge to keep it in place during storms. Nails can also help if you are dealing with a mild storm.

9. Seal Joints:

Your chances of dealing with a roof leak may increase if they come from joints on your roof. Rainwater can find ways to enter your home through gaps as well as chalk and aluminum flashing in areas where surfaces join.

These areas often include chimneys and valleys, and you can close them with roof sealant or cement. However, make sure the area is dry and debris-free before applying the sealant.

Save the sealant for smaller leaks and use new flashing to deal with larger cracks in your roof. Knowing which tools to use will reduce future issues and save you money on getting a new roof in the future.
